[16] These two forms are figured on Plate 10 of Eltringham's African Mimetic Butterflies.

[17] Acraea violae, the only representative of the group in S. India and Ceylon, is nevertheless a very abundant insect. It cannot, however, be said that it is definitely mimicked by any other species in this region.
